the bike has been standing for a while 75 miles between last MOT and current. The belts have no writing on at all but I suspect they are the originals as there's no mention of them been change in the history. It was the first thing to do when I got it home just didn't quite make it that far
Nelly thanks for the offer on the heads I will let you know when I take it apart on Sunday hopefully.
I dropped the engine out cause my mate has a better workshop than me and it will also be a good oportunity for Kiwi Chick to give it agood clean.
